Description

Technical Field

[0001] This utility model relates to the technical field of handicraft transport vehicles, specifically a transport vehicle for fragile handicrafts. Background Technology

[0002] As a common item in people's lives, handicrafts, especially ceramic, plaster, and glass handicrafts, need to be transported after processing and packaging. This requires the use of handicraft transport vehicles.

[0003] A search revealed that patent publication number CN219566170U discloses a glass craft transfer rack, including a support platform. The support platform is fixedly connected to a transfer box via screws at the top, and to a base plate via a bracket at the bottom. A placement frame is installed inside the transfer box, and a buffer structure is connected to the bottom of the placement frame. The buffer structure cushions and dampens the glass crafts placed inside from the bottom. Damping structures are also connected to both sides of the placement frame. The transfer rack uses multiple buffer springs connected to the bottom of the placement frame and multiple damping springs connected to the sides of the placement frame.

[0019] 1. In this utility model, through a series of coordinated structural arrangements, when workers transfer the protective packaging box containing handicrafts, the weight of the box itself exerts a downward force on the support plate. This downward force causes the first roller to press against the inclined block on the clamping mechanism. The inclined block, under this force, moves in a certain direction, causing the piston rod on the second piston assembly to move the piston plate towards the inside of the piston cylinder. The second piston assembly then... The gas discharged from the second piston assembly is transported to the first piston assembly through a connecting pipe. After the first piston assembly is filled with gas, the piston rod on the first piston assembly drives the clamping assembly to move linearly in a certain direction. The direction of movement of the clamping assembly is opposite to the direction of movement of the tilting block. When the first piston assembly is filled with gas, it can drive the clamping assembly to limit and clamp the protective packaging box containing the crafts placed on the support plate of the protective packaging box. Thus, this utility model can automatically limit and clamp the transported protective packaging box, eliminating the need for manual limit operation, reducing the workload of workers, and improving the efficiency of transporting protective packaging boxes containing crafts.

[0020] 2. In this utility model, through the coordinated arrangement of the buffer mechanism and other structures, when the protective packaging box containing handicrafts is transported by this equipment and subjected to certain bumps, the buffer mechanism can play a buffering and shock-absorbing role in the Y-axis direction, reducing the amplitude of the bumps experienced by the protective packaging box containing handicrafts, thereby improving the stability of the protective packaging box containing handicrafts during transportation.

[0043] like Figure 1-10 As shown, a fragile handicraft transport vehicle includes a movable frame 100. The four corners at the top of the movable frame 100 are connected to the four corners at the bottom of the support frame 300 through a buffer mechanism 200. The top of the support frame 300 is provided with a clamping mechanism 500 for clamping the protective packaging box of the handicraft. There are four clamping mechanisms 500, and the four clamping mechanisms 500 are arranged in a ring array. The four clamping mechanisms 500 can simultaneously limit and clamp the outer walls of the protective packaging box of the handicraft containing the handicraft. The support frame 300 is provided with a protective packaging box support plate 400 for placing the protective packaging box of the handicraft.

[0044] The clamping mechanism 500 is provided with a first piston assembly 510 and a second piston assembly 530, with the first piston assembly 510 located above the second piston assembly 530. Both the first piston assembly 510 and the second piston assembly 530 are composed of a piston cylinder 511, a rubber piston 512, a piston plate 513, an inlet / outlet pipe 514, and a piston rod 515.

The other end of the guide post 552 passes through the through hole on the outer wall of the first connecting plate 553 and is connected to the fastening plate 551. The outer wall of the guide post 552 and the hole wall of the through hole are clearance fit. Because the outer wall of the guide post 552 and the hole wall of the through hole are clearance fit, the movement of the second roller 555 can be limited and guided.

[0049] A second spring 556 is sleeved on the outer side of the outer wall of the guide post 552, and the second spring 556 is located between the first connecting plate 553 and the second connecting plate 554.

[0050] The guide post 552 has an external thread on its outer circumferential wall at the other end, and a threaded hole is provided on the outer wall of the fastening plate 551.

The other end of the limiting block 231 is installed in the limiting groove 222, and the outer wall of the limiting block 231 and the groove wall of the limiting groove 222 are in clearance fit. Since the outer circumferential wall of the buffer plate 230 and the inner circumferential wall of the mounting groove 223 are in clearance fit, and the outer wall of the limiting block 231 and the groove wall of the limiting groove 222 are in clearance fit, the movement of the buffer plate 230 can be limited and guided.

[0052] The limiting grooves 222 are arranged in a ring on the inner wall of the mounting groove 223. The upper surface of the buffer plate 230 is connected to the first fixing plate 211 through the first connecting column 210.

[0053] Push-pull handles 310 are installed at both the front and rear ends of one side of the top of the support frame 300. The push-pull handles 310 allow the operator to push the equipment. Self-locking casters are installed at the four corners of the bottom of the mobile frame 100. The self-locking casters allow the equipment to be moved or fixed on a horizontal surface.

[0054] Working Principle: During use, when workers transfer the protective packaging boxes containing handicrafts, they place the boxes onto the support plate 400. The weight of the boxes exerts a downward force on the support plate 400. This downward force causes the first roller 410 to compress the inclined block 560 on the clamping mechanism 500. The inclined block 560, under this force, moves in a certain direction. This movement causes the piston rod 515 on the second piston assembly 530 to move the piston plate 513 inward towards the piston cylinder 511. The second piston assembly 530 then exhausts gas, which is transported to the first piston assembly 510 via the connecting pipe 520. This gas filling the first piston assembly 510 causes it to... The piston rod 515 on the first piston assembly 510 drives the clamping assembly 550 to move linearly in a certain direction. The direction of movement of the clamping assembly 550 is opposite to the direction of movement of the tilting block 560. When the first piston assembly 510 is inflated, it can drive the clamping assembly 550 to limit and clamp the protective packaging box containing the crafts placed on the protective packaging box support plate 400. Thus, this utility model can automatically limit and clamp the transported protective packaging box, eliminating the need for manual limit operation, reducing the workload of the staff, and improving the transport efficiency of the protective packaging box containing the crafts. When the protective packaging box containing the crafts is transported by this equipment and is subjected to certain bumps, the buffer mechanism 200 can play a buffering and shock-absorbing role in the Y-axis direction, reducing the amplitude of the bumps experienced by the protective packaging box containing the crafts, thereby improving the stability of the protective packaging box containing the crafts during transport.

[0055] The above description is merely a preferred embodiment of this utility model and is not intended to limit the invention. For those skilled in the art, various modifications and variations can be made to this invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this invention should be included within the scope of protection of this invention.
